DIY Washing Machine Drum Repair

A washing machine has long been no longer a rarity and is an essential attribute of every home.

Its breakdown is always a nuisance, which is why there is a desire to quickly get the washing machine back into operation.

The washing machine tank is its main and fundamental part.

In this article, we will look at how to fix a problem related to the washing machine drum.

What is a washing machine drum?

It is in the tank that the moving parts of the washing machine, including the drum, are located.

The drum washes the laundry, even though it only comes into direct contact with the walls of the drum.

It is into the tank that water flows, and it seems that such a durable mechanism, although at the same time seemingly not performing its main work, cannot break.

However, there are things that can go wrong in the drum. Repairing a washing machine drum is quite a labor-intensive job, and to avoid having to redo it, you'll need to do it thoroughly.

If you want to get to the heart of the machine, you'll have to disassemble it completely, then remove the tub and disassemble that as well. The final step after repairing the washing machine tub - This is assembly in reverse order.

Types of tanks

Tanks can be made from:

• enameled,
• stainless steel and
• plastic.

Today, it is rare to find an enamel tank.

A stainless steel tank is reliable and can last for decades, but its production is quite expensive. Therefore, this type is found in more expensive models.

Most modern machines have a plastic tank. They're simple to manufacture, lightweight, and heat water quickly.

The disadvantage of a plastic tank is its fragility, but with proper use it can last for quite a long time.

Tank malfunctions

What can break in a tank?

1. BearingsIt's a very inexpensive part, but replacing it requires a lot of effort and time, risking serious damage to the shaft, pin, and other components. The bearings are located in the tank and are considered moving parts.
2. Drain hole near the tankMore precisely, the drain valve, which usually breaks or becomes clogged and requires cleaning.
3. ShaftTypically, a shaft problem is the result of bearing failure that has not been repaired.
4. Tank wallsAlso, the consequences of improper operation of bearings and shock absorbers, which lead to deformation of the tank walls under the influence of the centrifugal force of the drum.

Many serious breakdowns begin with bearing failure. Sometimes, untimely repairs can lead to replacing the entire tank.

How to disassemble a tank

Depending on the model of the washing machine, the tank can be:

• non-separable,
• collapsible.

Disassembling the tank requires a careful and painstaking approach.

Repair of a non-separable tank

Disassembly

Repairing a non-separable washing machine tank is much more difficult.

The question arises: why not make all tanks detachable? Because when temperatures fluctuate, the seal becomes loose due to loose fasteners.

1. Before disassembling the part, inspect the housing from all sides and locate the weld seam. This will be needed to drill holes for the fasteners for reassembly.
2. Armed with a drill and a thin drill bit, you need to drill 15-20 holes in a circle along the seam.
3. Next, this seam must be sawed through to access the inside of the tank. This is done with a hacksaw. This is time-consuming and requires patience. The maximum depth of sawing should not exceed 5 cm, otherwise irreparable damage to the tank walls can occur.
4. After this stage, the non-collapsible tank became collapsible and consists of two parts - front and rear.
   The front one is an irregularly shaped plastic ring with a hatch and a rubber cuff in the middle.
   The rear part consists of a drum with a drive mechanism, which we will remove. To do this, turn this part upside down and begin disassembling the shaft.
5. Be careful with the screw in the middle. To remove it, you'll need to apply a metal rod and hit it with a hammer. After this, the screw can be removed with a screwdriver.
6. Now it's the shaft's turn. It's removed using three wooden blocks (one small and two large). The drum is placed on the large blocks, and a hammer is used to strike the small block, which is then placed on the piston rod. Even though the piston rod appears sturdy, the blows must be applied with a certain amount of force—gentle, stronger, and even stronger—to avoid damaging the part. This should separate the drum from the drum.
7. You don't have to remove the bearings if there's no problem with them. A damaged tank may be to blame.
8. But bearings or seals often need to be replaced. In this case, you'll need a metal rod to gently strike the edges of the part with a hammer. Never strike just one edge, to avoid drilling into the part. Both bearings must be replaced if they are faulty.

After the work is completed, the machine is assembled in reverse order.

Assembly

How to glue a washing machine drum after repair?

The sawn parts of the tank are lubricated with sealant and connected.

Cold welding can be used.

Bolts are inserted into the drilled holes and secured with nuts.

The size of the bolts will depend on the diameter of the holes you drilled.

What to do if the tank body is deformed?

First of all, it is necessary to analyze the nature of the damage and the scale of the work.

If the tank is plastic

If the tank is plastic, it may have cracks that are causing the water leak.

We immediately rule out the option of soldering the crack, because this is a conditional repair of the washing tanks, which will not last very long.

The best option is to replace the tank with a new one. A metal tank is more expensive than a plastic one.

If the tank is made of stainless steel

If you're considering repairing a stainless steel tank, welding is a perfectly reasonable option. Of course, it's best to trust an experienced welder, who will do the job quickly and accurately. After welding, you can paint the weld with waterproof enamel to extend the life of the part.

Keep in mind that sealant, no matter what quality, and cold welding will not solve the problem.

Repair in case of deformation

If the tank is deformed, repairs are carried out as follows:

1. You'll need a hammer and a wooden block. If the damage is minor and there are no holes, no other tools are needed.
2. The dent needs to be heated using, for example, a gas torch. The outside of the tank is heated.
3. The hammer strikes the block not to make a dent, but to make a bulge, while the metal is still hot.

Drain repair

If the problem is in the drainage system, the action plan is as follows:

1. Check the drain hole for a blockage. You may need to remove limescale; sandpaper is a good option for this.
2. The sealing rubber and cuff also require careful inspection. Sometimes the rubber becomes hardened and cracks, in which case the only solution is to replace it with a new one.
3. The drain valve has contacts. It's a good idea to use a multimeter and check them after thoroughly cleaning them. If the resistance is 1, the part will need to be replaced, as it's clearly faulty.

Of course, repairing a washing machine's tub yourself is no easy task. Properly disassembling, repairing, and, most importantly, reassembling the unit flawlessly at home is practically a feat!
